Braking response and brake application control is significantly better with disc brakes even under the toughest braking conditions. Tests confirm that disc brakes out perform 'S' cam drum brakes in extended downhill driving situations. The smaller brake chamber used consumes less air than standard drum brakes to perform a similar task.

Braking Performance

With the inherent high efficiency of disc brakes the vehicle stops more easily in a straight line and less distance. The disc brake does not suffer from fade under constant brake pressure whereas the drum brake needs gradually increasing brake pressure to maintain the same brake performance.

Maintenance

Exchanging air disc brake pads take 1/4 of the time of typical 'S' cam drum brake linings resulting in large time savings. Reduced parts inventory is achieved through the use of the same brake components on all the axles fitted with 19.5" and 22.5" wheels. The expected longer life of the main service items also results in fewer service intervals.
